ccconverter: drop data when overflow on extracting cea608 from cc_data
...
If the buffer overflows, then drop rather than causing a failure and
fropping the output buffer indefinitely. This may have caused downstream to
be waiting for data the will never arrive.

ccconverter: fix framerate passthrough with malformed input
...
If an input is malformed (only produces cea608 field 1 cc_data) then
when in passthrough we would effectively be dropping every second cea608
on output as we would not store any unused cea608 data.
Fix by having all code paths go through the framerate conversion code
which will store and retrieve any relevant data across buffers.

ccconverter: ensure correct ordering of cea608 across output buffers
...
e.g. if a 60fps output is configured, we can only produce a single field
of cea608 that must alternate between field 1 and field 2.
